Having Trouble Inserting Elements

[bigmasterdrago]

Part of the problem is that I don't know which terms mean what on the Horizon page. In the mean anomaly tab there is an E+2 in the figure. It may be that means to move the decimal over to the right 2 times. For E-1 that would be to the left 1 decimal place. I just do not know. Not sure what the time reference is. When I do the entries and click OK, I get the hourglass for a long time, maybe 30 seconds. Then it will find it in a search. I'm clearly doing something wrong due to the fact that a Horizons ephemeris is nowhere close to the one generated in ST4. I've included images of both ephemerides and the elements I got from Horizons. I also have shown what ST4 has done to the elements that I inserted from the Horizon elements screen. Very much different. Why?
